Answer this question truthfully
### Question: What causes Hair loss?
### Response: A sudden physical or emotional stress may cause one-half to three-quarters of the hair throughout your scalp to shed (called Telogen effluvium). You will notice hair coming out in handfuls while you shampoo, comb, or run your hands through your hair. You may not notice this for weeks to months after the episode of stress. The hair shedding will decrease over 6 - 8 months.
Cause of this type of hair loss are:
Childbirth Crash diets, especially those that do not contain enough protein High fever or severe infection Major surgery, major illness, sudden blood loss A number of medications, including retinoids, birth control pills, beta-blockers, certain antidepressants, NSAIDs (including iburpofen) and calcium channel blockers Severe emotional stress
Other possible causes of hair loss, especially if it is in an unusual pattern, include:
Alopecia areata -- bald patches that develop on the scalp, beard, and, possibly, eyebrows. Eyelashes may fall out as well. Anemia Autoimmune conditions such as lupus Burns Certain infectious diseases such as syphilis Excessive shampooing and blow-drying Hormone changes Nervous habits such as continual hair pulling or scalp rubbing Radiation therapy Thyroid diseases Tinea capitis (ringworm of the scalp) Tumor of the ovary or adrenal glands
